Advantages of OGFD Air Screw Compressor:

  • Water cooler
        The plates are made of special 304L stainless steel, offering corrosion resistance and high thermal efficiency, which reduces pressure and temperature differentials and ensures the system operates under near-isothermal compression. The system features a compact design, requires less cooling water, minimizes pressure loss, enhances durability, and is easy to clean and maintain.
  • Water filter

        The housing is made of stainless steel, offering high filtration precision and a long service life, ensuring the system remains clean and free of impurities.


  • Relief valve

        The independently designed unloading valve (Patent No.: ZL200520058468.2), specifically engineered for vortex characteristics, enables fully sealed operation in screw compressors, ensuring stepless air delivery from 0 to 100%.

AIRERA 55kW Screw Air Compressor: Frequently Asked Questions (FAQ)
Why is the 55KW model ideal for the pharmaceutical and food industries?
These industries require absolute air purity. AIRERA’s 55KW oil-free technology provides ISO Class 0 certified air, ensuring that no oil vapor comes into contact with the product, thereby preventing costly recalls and ensuring consumer safety.
Can a 55KW air-cooled unit operate effectively in high-humidity regions?
Yes. Our 55KW unit features an enhanced moisture separation system and a high-efficiency air cooling array. The oversized radiators are designed to prevent heat buildup even in humid, tropical environments, ensuring stable discharge temperatures.
What makes AIRERA's oil-free rotors different from competitors?

We use a multi-layer polymer coating combined with stainless steel substrates in critical areas. This dual-protection approach prevents coating peel-off and rotor corrosion, maintaining high volumetric efficiency for a much longer service life.
